CULTIVATOR.

SPECIFICATION' forming part of Letters Patent No. 276,718, dated May 1, 1883. Application tiled January 8, 1883. (No model.)

To all whom t may concern:

Be it known that I, HANs H. SATER, of Dubuque, in the county of Dubuque and State of 1owa,have invented a new and useful Improvement in Gultivators; and I do hereby declare that the following is afull, clear, and exact de,- scrption of the same.

My invention relates to an improvement in cultivators; but it relates more particularly to improved coupling devices for connecting the j plow-beams to the axle and framework, the object being a simple and inexpensive construction, easy in adjustment and operation, and durable and effective in use.

The invention consists, rst, in the peculiar novel construction and arrangement of the coupling proper; further, in peculiar stops or sleeves on the axle for limiting the movementof the axle-sleeve; further, in peculiar draft-attaching devices; and, nally, iu the general construction of the cultivator, and in novel details and combinations` all fully hereinafter explained. t

The invention is illustrated in drawings which accompany this specification, and in which Figure lis a perspective view of the axle, one ofthe beams, and the coupling. Fig. 2 is aside elevation of the coupling. Fig. 3 is a detail of the cross b1ock; Fig. 4, a detail of the corner-clip; Fig. 5, a detail of the sandcapfor the axle; Fig. 6, details of the coup-1 ling; Fig. 7, a modification of the fork-connection.

A in these drawings represents the arched axle of a cultivator, constructed of course of metal, and having ateach end a plain bearing for the carrying-wheels. i

B B represent the plow-beams, and G one o the couplings by which the beams areconnected to the axle.

The horizontal part of the axle, on each side of the central arch, is made cylindrical to re ceive a sleeve, D, having a. correspondingly cylindrical internal bore and a fiat front face, 1, horizontally serrated or corrugated. This ual movement on the axle, rst, by cornerclips E, Fig. 4, at the base of the arch; land,

second, by sand-caps F on the axle between .SO

the sleeve and the carrying-wheel bearings.

The corner-clps are composed of a tubular portion, 2, which is clamped upon the base of the arch by a. bolt and ears 4 4 and projections 5 5 6, which are bent down, as shown in Fig. 1, and bind firmly upon the axle, the projection 6 forming a stop against which the axleslee-ve bears, and by which, as before remarked, any longitudinal movement of the latter is prevented.

The sand-caps F are shown in Fig. 5. They are of tubular form and are provided with ears 7 7, by which they are clamped upon the axle, and with a projecting shield or cap, 8, which extends over the bearing of the carrying-wheel and prevents the dust and gritfrom entering. Thedraft-attaching devices are connected to these caps, and also braces which support the ton gue. Similar braces for the tongue are also connected to the clips E.

G represents a toothed sleeve, adapted to engage with the serrated face of the axle-sleeve D. This sleeve is shown in detail in Fig. 6.

It is provided near each end with a true cylin-` drical bearing, 8, and at the upper end with a, squared projection, 9. A bolt, H, passes through the sleeve, and is secured rigidly to it by a washer, 10, having a square countersink, 1l, which iits over the projection 9 on the sleeve. At the lower end the bolt H is squared, asuat 12, while the internal bore of the sleeve is of similar shape.

I is the fork-connection. (Shown separately in Fig. 6.) Its lower arm, 13, has an eye, 14, which works freely upon the lower bearing of the sleeve G. The attachment of the fork I to the upper bearing of the sleeve G is made through an independent eye, J, having a perforated arm, 15, provided with a notch, 1li, and shoulder 17. The fork I and eye J are connected by a holt, K, and when the parts are in position the end of the fork bears against the shoulder 17, while the notch 16 engages V,with the end of aJ rib, 18, formed integral with the fork. The fork when in place has :a free horizontal movement on the bearings.

The toothed sleeves are held in close contact by the peculiar loop shownatL,which has two horizontal links or eyes, 19, with a space, 20, between them.l The loop is slipped over the axlesleeve, while the sleeve Gis passed through the links, (see Figs. 1 andi) and .a set-screw, 2l, draws the parts together. It will now be readily apparent that a universally-yielding coupling is provided, thev`ertical movement IOO being that of the horizontal sleeve on the axle, while the fork moves horizontally on the bearings upon thevertical sleeve.

M Nare the drag-bars. They are connected by means of bolts to arms 22, formed solid with fork-connection adapted to Wooden drag-bars, the construction of which will be readily understood from the drawings.

Having described my invention, I claiml. The combination, with the axle and its toothed sleeve,of the vertical toothed sleeve G, engaging with the said sleeve on the axle, and having bearings formed directly uponv its ends, and a bolt passing through said sleeve `and bearings, a drag-bar, and the fork I, connected to the drag-bars and mounted upon the bearings on the ends of the said sleeve G, substantially as described.

2. The combination of the axle and its toothed sleeve, the vertically-toothed sleeve G,

,having bearings at'its ends, thedrag-bar, the 3o forked connection I, connected to the drag-bar and mounted on the bearings ofthe sleeve G, and the loop embracing the said axle and sleeve G, and having the setscrew, substantially as described.

3. Combined with the arched axle A, the clipE, having earstt for attaching the tonguebraces, and the prongs 5 5, adapted to be bent down to bear directly upon the axle at the base of the arch, for the purpose set forth. t

4. The combination, with the vertical sleeve connected to the axle-sleeve, ot' the fork having one arm connected directly to the bearing or journal formed on such vertical sleeve, and the eye J, which forms the connection between the otherarm ofthe fork and the sleeve G.

5. Combined with the dragbars M N, the cross-block O, having brace connection 24, beveled and tjanged ends 23', and the adjusting-slots 25 in such ends, substantially as deu scribed.

In testimony whereo'I have signed mynaine to this specitication in the presence of two subscribing witnesses.
